Obviously, we have no way of knowing what our future will be; however, as Christians, we know the one who knows--God.
We should not worry about the future, because our times are in His hands (Psalm 31:15). In other words, God will give you what you need when you need it.
Therefore, it is no surprise that Jesus repeatedly tells us not to worry: "Do not worry about tomorrow" (Matthew 6:34).
Again, Jesus emphasized that God loves and cares for us, and we therefore should not worry about our life: "Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more important than food, and the body more important than clothes? Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they? Who of you by worrying can add a single hour to his life?" (Matthew 6:25-27).
Although you don't know what God has in store for you, be assured that He has a good plan for your life (see Romans 8:28). Because He has such a good plan for you, there is no need to worry about life. Although you don't know what tomorrow holds, you have the opportunity to know the one who holds tomorrow!
